AAAA batteries of 9V crown

There is a wireless light switch at work, it lies on my desk. It is time to change the batteries, open, and see AAAA batteries.

As it turned out to be a very rare standard for Russia, I found in Chip and Dip a pair of such batteries for 150 rubles. Toad strangled immediately.

But knowledgeable people suggested that some Krone alkaline batteries labeled 6LR61 consist of 6 AAAA cells. Salt crown 6F22 will not work.

For the experiment, 2 Kroons of manufacturers were purchased: GP, Kodak (average price of kroons is 70r).
Crown GP Super did not meet expectations, it consists of rectangular alkaline elements.


But Kronak Kodak MAX contains 6 AAAA batteries in itself.

According to information from wikipedia, AAAA batteries can also be found in the Energizer Crown.
